Specification of Letters Patent.

Patented J 111.67, 1914.

Application filed April 18, 1912. Serial No. 691,637.

To all whom it may concern Be it known that we, HIRAM CnPHAs UPTON and JOHN EDwI-N Urron, citizens of the United States, and residents of Atwater, in the county of Macoupin and State of Illinois, have invented certain new and useful Improvements in Safety-Stirrups, of which the following is a specification, reference being had to the accompanying drawings.

This invention has relation to certain new and useful improvements in stirrups, S0 .0011- structed that it will be impossible for the riders foot to get caught therein; and .theobject of our invention is to provide a device of this general character, of a simple and inexpensive nature, and of a compact and durable construction, which will be capable of convenient attachment to a saddle, the arrangement being such that it will be impossible for the riders foot to get caught in the stirrup in dismounting or in case the rider is thrown from his saddle.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claim, it being further understood that changes in the specific structure shown and described may be made within the scope of the claim, without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views: Figure 1, shows an elevational view of the safety stirrup embodying our invention. Fig. 2, is a section on line 2, 2 of Fig. 1. Fig. 3, is a sectional view disclosing the securing arms as displaced, insuring the detachment of the stirrup proper from the stirrup yoke.

In our present invention we provide a safety stirrup including two distinct separable members to-wit: a carrying yoke and a stirrup bow, the latter giving support to a detent detachably connecting said bow yoke.

In the drawings the numeral 1, designates a metal bowed yoke having each of its ends 1, provided with a square opening 3, as shown in Fig. 3. This yoke further has the integral strap loop 2, to receive the end of the stirrup strap A. The ends 1, of the yoke are slightly flared outward so that their inner faces extend at an angle to one another, as will be understood in referring to Fig. 1.

In connection with the yoke described, we employ a U-shaped stirrup 4, each end a, of which has a splayed aperture 6, shown in Fig. 3, these apertures being arranged to register with the openings 3. As shown, the ends a, of the stirrup 4, are held between the ends 1', of the yoke.

In order to detachably secure the stirrup 4, to the yoke 1, we employ a detent compris ing the bar 9, having a mortise 18, and the bar 11, having a tenon 19, as shown in Fig. 1. Each bar .ends in a square lug :8, the ends 7, of these lugs being chamfered as shown in Figs. 2 and 3.

The bars 9 and 11, are hingedly connected by means of the pivot bolt 13, passing through the mortise and tenon of these members 9 and 11, in the manner shown. Each bar further has an ear, the ears being marked 15 and 14, respectively.

Held upon the bolt 13, is a spring having a centrally positioned coil encircling said bolt as shown in Figs. 2 and 3, while the arms 16, of this spring extend in opposite directions and are held within the ears 14 and 15. By means of this spring 16, the bars 9, and 11, are normally held in alinement.

In their normal position as is shown in Fig. 2, the ends of the members 9 and 11, lie against the inner faces of the ends a, of the stirrup 4, this construction also being shown in Fig. 1. In this condition of the detent the square lugs 8, are held within the splayed apertures 5, as well as within the square openings 3. As shown in Fig. 2, the member 9, has its ends provided with the angled faces 10, which serve as stops, to limit the movement of these two pivotally connected members 9 and 11. In Fig. 3, the stop surface 10, is shown as resting against the ends of the member 11, limiting the outward movement of these members. In this condition of the detent the chamfered ends 7, of the lugs 8, are clear of the yoke openings 3, so that the stirrup 4, will instantly drop away from the yoke. The splayed openings 6, permit the movement of these lugs in one direction as shown in Fig. 3. Now, should the rider be accidentally thrown as soon as his foot encounters the detent, the same will be actuated to carry the lugs 1, out of the seats 3, so that the riders foot will at once become detached from the stirrup. The stirrup 4, can, of course, again be readily attached to the bow though it is impossible to remove the detent from the stirrup for apertures.

the reason that the ends of the bars 9 and 11, cannot be withdrawn from the splayed This is owing to the fact that when the stop surface 10, encounters the end of the member 11, the ends of the bars 9 and 11, contact with the inner faces of the stirrup 4, as clearly indicated in Fig. 3.

The stirrup is simple and inexpensive in construction and both durable and efiicient in operation and the same can be instantly detached by actuating the detent.

Having thus described our said invention, what we claim as new and desire to secure by United States Letters Patent is:

A safety stirrup comprising, a bow yoke having each of its ends provided with a square opening, a U-shaped stirrup each end of which has a square splayed aperture to register with one of said square openings,

the ends of said stirrup being held between the ends of said yoke, a detent comprising two similar bars each having a square chamfered lug reciprocating within the splayed aperture and an opening, one of said bars having a stop surface to limit the movement of said members, a bolt pivotally connecting said members, each of said members having an ear, and a spring coiled about said bolt,

the ends of said spring being held within said ears, all arranged substantially as and for the purpose set forth.

In testimony whereof we affiX our signatures, in presence of two witnesses.
